etc., and has for its object to provide an improved process of manufacturing a fabric having a mottled appearance as illustrated inthe accompanying drawing, wherein,

Figure 1 is an elevation of a piece of the fabric.

The fabric is composed of white thread silk in the gum (also known as Japan tram, natural silk, and pure silk) twisted together with either white artificial silk thread (made from woody fibers or cellulose in the usual manner) Aor white cotton; thread and then knitted or woven to form the fabric into a sock, stocking, undergarment, necktie, etc., after which the fabric is boiled in a soap bath to remove the gum from the thread silk. After degumming, the fabric is then dyed by using a combination of dyestuffs and chemicals thatv will dye the artificial silk or the cotton but not the thread silk. While the fabric is being dyed, a

the artificial silk or the cotton the color of the dye. By reason of thev fabric being formed of thread silk twisted together with either artificial silk thread or cotton thread and then knitted or woven, the thread silk and the artificial silk or the cotton become interspersed irregularly throughoutl the fabric, the dyeing of the'fabric in the manner hereinabove described resulting in the production of a fabric having a mottled appearance because of the presence of the interspersed White fibers of the thread silk 'and the colored fibers of Athe artificial silk or the cotton in the fabric.

l In practice, various dyestufls may be used to color the artificialsilk or the cotton different colors and still leave the thread silk white. For example, if it is desired to dye the artificial silk or the cotton black, sulfur black dye consisting of sulfid of sodium, sulfur black, glue, and salt is employed, for the reason that same will dye the artificial silk or the cotton but not the thread silk, the glue being used to prevent the sulfid of sodium from eating up the thread silk. In order to dye the artificial silk or the cotton tan or navy blue, tan or navy blue coloring matter and phosphate of sodium may be used so as to color the artificial silk or the cotton tan or navy blue and leave the thread silk white. It should be understood that dyes other than black, tan, or navy blue may be used, and, furthermore, basic colors may be combined if so desired.

The object of weaving the silk in the gum and degumming it after it has been woven in -a fabric is to give the fabric a crinkled or wavy appearance. v

I claim:

1. The herein-described process of manufacturing fabric consisting in twisting together thread silk in the gum with either artificial silk or cotton and then knitting or weaving same, degumming the thread silk, and then dyeing the artificial silk or the cotton.

2. The herein-described process of manufacturing fabric consisting in twisting t0- gether thread silk in the gum with either artificial silk or cotton and then knitting or weaving same, degumming the thread silk by boiling the fabric in a soap bath, and

then dyeing the artificial silk or the cotton.

3. The herein-described process of manufacturing fabric consisting` in twisting together white thread silk in the gum with either white artificial silk or cotton and then knitting or weaving same, degumming the thread silk, then dyeing the fabric with such combination of dyestuffs and chemicals as will dye only the artificial silk or the cotton, and lastly boiling the fabric to remove the dye from the thread silk so as to leavethe latter white.

4. The herein-described process of manufacturing fabric consisting in twisting together white thread i silk in the gum with either white artificial silk or cotton and then knitting or weaving same,`degumming the thread silk by boiling the fabric in a soap bath and then dyeing the.fabric with such combination of dye stuffs and chemicals as willaffect only the artificial silk or cotton.`

5. The herein-described process of manumove any possible dye that mayhave lodged 10 in the thread silk during the dyeing process. ln testimony whereof I hereunto affix my signature in the presence of tWo Witnesses.
